FIELD OF THE INVENTION

Embodiments included herein generally relate to creating a desired listening experience for users in home entertainment systems. More particularly, embodiments relate to creating the desired listening experience for the users by use of a media remote device in conjunction with a media content player, a television and a plurality of speakers.

BACKGROUND OF THE INVENTION

When experiencing media/content having an audio component (e.g., movies, video, music, games, Internet content, etc.), different users may desire different listening experiences. For example, users may differ in their preferences for volume and other audio features (bass, treble, balance, etc.), sound mode (movie, music, surround decoder, direct playback, unprocessed, etc.), movie mode (standard, sci-fi, adventure, drama, sports, etc.), music mode (concert hall, chamber, cellar club, music video, 2 channel stereo, etc.), as well as any other audio characteristics.

Media/content such as movies, however, have a default audio track typically established by the content provider. Thus, what is needed is a way to customize the audio component of media/content to suit the listening preferences of different users.

SUMMARY OF THE INVENTION

An embodiment includes a method for creating a desired audio effect. The method operates by causing a plurality of speakers to play test signals, where each test signal is specific to one of the speakers. Frequency responses of the speakers resulting from the playing of the test signals are recorded. One or more filters matching an audio profile selected by a user is created. Then, the filters are applied to the recorded frequency responses to obtain filtered transformations of the speakers. The filtered transformations are applied at the speakers to thereby achieve the user audio profile.

Another embodiment includes a system having a media content player that is operable to cause a plurality of speakers to play test signals, where each test signal is specific to one of the speakers. Frequency responses of the speakers resulting from the playing of the test signals are recorded. The media content player creates one or more filters matching an audio profile selected by a user. The media content player applies the filters to the recorded frequency responses to obtain filtered transformations of the speakers. The filtered transformations are applied at the speakers to thereby achieve the user audio profile.

Another embodiment includes a tangible computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the computing device to perform operations comprising: causing a plurality of speakers to play test signals, each test signal being specific to one of the speakers; receiving from a remote device recorded frequency responses of the speakers resulting from the playing of the test signals; creating one or more filters to match an audio profile selected by a user; applying the filters to the recorded frequency responses to obtain filtered transformations of the speakers; and transmitting the filtered transformations to the speakers; wherein the filtered transformations are applied at the speakers to thereby achieve the user audio profile.

Another embodiment includes a method of using aggregating volume information to enhance audio playback of content. The method includes the steps of receiving requested content from a server; determining if the received content includes aggregate volume statistics; playing the received content; continuously adjusting volume of the received content based on the aggregate volume statistics, if it was determined the received content included aggregate volume statistics; monitoring changes in volume made by a user while viewing the received content; and providing information reflecting the monitored volume changes to the server.

DETAILED DESCRIPTION OF THE INVENTION

Provided herein are system, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for creating an improved audio experience for a user.

Customizing Audio Components to Match User's Audio Profile

FIG. 1 illustrates a home entertainment system 100 for creating an improved audio experience for a user. In an embodiment, the home entertainment system 100 is a multi-speaker home theater environment where a user 102 sits in an appropriate viewing location in chair 104 in view of media content television 108 with a media remote device 106.

In an example embodiment, the user 102 may place the speakers 122 in any location and/or configuration.

FIG. 2 illustrates another embodiment of the home entertainment system 100. FIG. 2 is similar to FIG. 1, but shows media content player 112 as external to the television 204.

FIG. 3 is another embodiment of the home entertainment system 100. FIG. 3 is similar to FIG. 1, but includes additional components in media entertainment system 302.

In particular, in the example of FIG. 3, media content player 112 is connected to a stereo 304. The audio and video output of stereo 304 may be connected to television 204. A line out of stereo 304 may be a non-amplified signal output port connected to a cascaded device 306 for sound enhancements, according to an example embodiment. The cascaded device 306 may transmit its output to wireless and/or wired speakers 122, according to an embodiment. The cascaded device 306 may include but not be limited to a preamplifier, an equalizer device, a microphone, a speaker, a tablet computer, a personal desktop, a laptop/mobile computer, a handheld computer, a server computer, or an in-appliance device, according to example embodiments.

FIG. 4 illustrates media content player 112, according to an example embodiment. The media content player 112 may include a TV System on a Chip (TV SOC) 402, a transmitter 404, a receiver 406, and a Network Interface Circuit (NIC) 408. According to an embodiment, the TV SOC 402 communicates with the transmitter 404 and the receiver 406. The TV SOC 402 may be configured to receive video streaming from NIC 408 and integrate high efficiency video codec to the received video streaming, according to an embodiment. The TV SOC 402 may use a High Efficiency Video Codec (HEVC) or H.265 standard. The TV SOC 402 may transmit the integrated video to television 204 or to the media content television 108.

FIG. 5 illustrates wireless and/or wired speakers 122, according to an example embodiment. The wireless and/or wired speakers 122 may include a receiver 502, amplifier circuitry 504, a speaker 506, and a transmitter 508.

FIG. 6 illustrates a media remote device 106, according to an example embodiment. The media remote device 106 may include interactive buttons 602 (e.g., volume, channel, up-down-left-right arrows, select, menu, etc.), a transmitter 604, a receiver 606, a microphone A 608, a microphone B 610, and a Central Processing Unit (CPU) 612.

According to an embodiment, microphone A 608 is configured to receive human voice and has a frequency response range of 300 Hertz (Hz) to 3000 Hz. Microphone B 610 is configured to receive background noise and has a frequency response range of 20 Hz to 20 kilohertz (kHz). CPU 612 operates to discern between audio voices and background noises received by microphone A 608 and microphone B 610.

FIG. 9 is a method 900 for creating a desired audio experience for a user, according to an example embodiment. Method 900 can be performed using, for example, system 100 of FIGS. 1-3.

Generally, method 900 operates to configure the components of system 100 so as to customize the audio experience for user 102. First, system 100 determines the user 102's audio preferences (this is generally covered by steps 902-908). Second, system 100 determines the current audio response of the components of system 100 (this is generally covered by steps 910-934). Third and finally, system 100 modifies the audio response of the components of system 100 so as to align such audio response with the user 102's audio preferences (this is generally covered by steps 936-946). Method 900 shall now be described in detail.

In steps 902 and 904, user 102 turns on the television 108/204 and media content player 112 (in an embodiment, media content player 112 will automatically turn on when the television 108/204 turns on, if these components are integrated into a single unit as shown in FIG. 1).

In step 906, the user 102 uses remote 106 to communicate with media content player 112 and set his audio preferences. In an embodiment, the media content player 112 displays a series of menus on television 108/204 to enable the user 102 to select and define a plurality of audio effects. Such audio effects include but are not limited to: delay between front and back speakers; delay between right and left speakers; volume and other audio features (bass, treble, balance, midrange, fading, etc.); sound mode (movie, music, surround decoder, direct playback, unprocessed, etc.); movie mode (standard, sci-fi, adventure, drama, sports, etc.); music mode (concert hall, chamber, cellar club, music video, 2 channel stereo, etc.); as well as any other audio characteristics. The media content player 112 saves the user 102's audio preferences (which are also called the user 102's audio profile).

In an embodiment, the user 102 may define different audio profiles for different types of content, such as different types of movies (e.g., action, drama, comedies, etc.), different types of music (e.g., pop, country, alternative, etc.), different types of venues (e.g., stadium, concert hall, intimate night club, etc.), different types of technical features (subwoofer on/off; rear speakers on/off; 2 channel mono; etc.), as well as any other combination of audio features the user 102 may wish to define.

Also in step 906, user 102 selects one of his audio profiles.

The room in which the user 102 is seated may include acoustic anomalies, such as room configuration or furniture that affect acoustics. Also, the acoustic anomalies may include the frequency response of speakers 110, 122 and 206, as well as the frequency response of the interaction between speakers 110, 122 and 206. Another acoustic anomaly may be coupling, reflections, or echoes from interaction between speakers 110, 122 and 206 and the walls of the home entertainment system 100. An additional acoustic anomaly may be audio effects caused by dynamic conditions of temperature, humidity and changing absorption.

These acoustic anomalies may not be detected by media content player 112 if background noise is present. Thus, in step 908, media content player 112 prompts the user 102 to silence any background noise. Also, media content player 112 turns off any background noise reduction algorithms in components of system 100.

In step 910, media content player 112 prompts the user 102 to ensure the speakers 110, 122, 206 and stereo 304 are placed in their desired position. In an embodiment, user 102 can place speakers 110, 122, 206 and stereo 304 in any desired location and configuration. In the following steps, regardless of the location of speakers 110, 122, 206 or stereo 304, media content player 112 will accordingly adjust the operation of components of system 100 to achieve the user 102's selected audio profile.

In step 912, media content player 112 prompts the user 102 to place the media remote device 106 in the desired position. In an embodiment, the desired position of remote 106 is where the user 102 will normally sit (i.e., chair 104).

In step 914, media content player 112 may instruct the user 102 to remain stationary. Media content player 112 also may instruct user 102 to keep the remote 106 stationary. Having both the user 102 and remote 106 stationary during the following steps may enhance the ability of media content player 112 to achieve the user 102's selected audio profile.

As people age, gradual hearing loss may occur. In an embodiment, media content player 112 may compensate for such hearing degradation. Accordingly, in step 916, media content player 112 transmits a tone to test the audible hearing frequency range of user 102. Media content player 112 may transmit tones stepping in increments of frequency until the tones are no longer audible. The process for transmitting tones may begin with transmitting the tone at the lowest frequency, according to an embodiment. In an alternative embodiment, the tone may begin with transmitting the tone at the highest frequency.

In step 918, media content player 112 asks the user 102 if the tone was audible. If user 102 answers “Yes” via the remote 106, then in step 920 the media content player 112 determines if the last transmitted tone was at the maximum allowable frequency. If not, then in step 922 the frequency is increased by some increment (such as 10 Hz in a non-limiting example), and in step 916 the tone at the higher frequency is transmitted.

If at step 918 the user 102 answered “No,” then in step 924 the media content player 112 stores the maximum audible frequency in the user 102's audio profile. In an embodiment, media content player 112 uses the maximum audible frequency as a threshold for user 102. Specifically, in an embodiment, media content player 112 may not play sounds above the maximum audible frequency when the user 102's selected audio profile is being used.

In step 926, media content player 112 transmits a test signal from transmitter 404 to speakers 110, 122 and 206. In an embodiment, media content player 112 may send a different test signal to different speakers 110, 122 and 206. In step 928, speakers 110, 122 and 206 receive the test signal(s) via their respective receiver 502. According to an embodiment, the test signal may include a chirp signal, an example of which is shown in FIG. 7. A chirp signal is a sinusoid that sweeps rapidly from a starting frequency to an end frequency. The chirp waveform may range in amplitude from +1 volt to −1 volt. A desirable feature of the chirp waveforms is its small crest factor and flat frequency response. The flat frequency response of the chirp signal, as shown in FIG. 8, is used to equally test all frequency components of a system.

In an alternative embodiment, the test signal may include a step signal. A step signal may be useful to evaluate the transient response of a system under test.

In step 930, speakers 110, 122 and 206 play their respective test signal. In an embodiment, for each speaker 110, 122 and 206, amplifier circuitry 504 plays the test signal via speaker 506. In an embodiment, speakers 110, 122, and 206 sequentially play the received test signal. Alternatively, the speakers 110, 122 and 206 play the test signal at the same time.

Also in step 930, the remote 106 receives the test signal played by speakers 110, 122 and 206 via microphone A 608 and microphone B 610. In doing so, remote 106 processes and/or records the frequency response of speakers 110, 122 and 206. Where the test signals differ by speaker 110, 122 and 206, remote 106 also timestamps when it received the test signal from each speaker 110, 122 and 206.

In step 932, media content player 112 receives the recorded frequency responses of speakers 110, 122 and 206 from media remote device 106. Media content player 112 also receives from remote 106 the timestamps (when available).

In step 934, media content player 112 calculates the respective distances of the remote 106 to each of the speakers 110, 122, and 206. In an embodiment, media content player 112 calculates these distances based on the delay of the test signal between when the test signals were issued by media content player 112 (in step 926) and heard by remote 106 (in step 930). In an embodiment, because speakers 110, 122 and 206 were assigned different test signals, media content player 112 is able to calculate the distance for each.

In step 936, media content player 112 creates a filter(s) for the selected audio profile. The filter(s) may take into consideration the respective frequency responses (from step 930) and distances (from step 934) of the speakers 110, 122 and 206. As discussed below, the filter(s) will operate to transform the frequency response of each speaker 110, 122 and 206 to the user 102's selected audio profile. According to an embodiment, media content player 112 generates a linear time invariant (LTI) filter for the selected audio profile. The LTI filter is generated based on a frequency response of the selected audio profile (or each component thereof) and will be respectively convolved with the recorded frequency response of speakers 110, 122 and 206. In doing so, media content player 112 strives to modify the frequency response of speakers 110, 122 and 206 to match the user 102's selected audio profile. In an embodiment, media content player 112 may also strive to eliminate unwanted frequency components in the recorded frequency responses of speakers 110, 122 and 206. Such unwanted frequency components may be the result of acoustic anomalies discussed above.

Embodiments may use two types of LTI filters, Finite Impulse Response (FIR) filters and/or Infinite Impulse Response (IIR) filters. An advantage of using a FIR filter is its ability to reduce or eliminate phase distortion. As such, a FIR filter may be generated by the media content player 112 to reduce or eliminate phase adjustments. Alternatively, a FIR filter may be designed to create particular desired phase adjustments. For example, the FIR filter may be designed for the theater environment audio effect, where a phase adjustment of around 70 degrees may be desirable. An advantage of an IIR filter is it may be more computationally efficient.

In another embodiment, media content player 112 may generate a combination of IIR and FIR filters for each speaker 110, 122 and 206 in step 436.

Also, in step 936, media content player 112 may generate filters to compensate for delays associated with the distance of speakers 110, 122 and 206 determined in step 934.

In step 938, media content player 112 applies the filters to the frequency responses of speakers 110, 122 and 206 to create a filter transformation for each of the speakers 110, 122 and 206.

In step 940, media content player 112 transmits the filter transformations to their respective speakers 110, 122 and 206, as well as to stereo 304.

In step 942, speakers 110, 122 and 206 and stereo 304 respectively receive the filter transformations.

In step 944, the filter transformations are applied to each of the speakers 110, 122 and 206 and the stereo 304. In an embodiment, each speaker 110, 122 and 206 processes and applies the received filter transformation with amplifier circuitry 504. In an alternative embodiment, the filter transformations may be applied by stereo 304. In an embodiment, the stereo 304 may apply the filter transformations to the line out which is connected to the cascaded device 306.

In step 946, user 102 selects content from the media content player 112. In response, media content 112 plays the content on television 108/204 using the selected audio profile in the manner discussed above.

Crowd-Sourcing Volume Information for Enhanced Playback of Content

In another aspect of embodiments of the invention, FIG. 10 illustrates a network environment for analyzing and applying volume statistics for users 102. The system 1000 includes a set of environments 1002-1 through 1002-N, a network 1004, and an aggregate server 1006, according to an embodiment. Each environment 1002-1 through 1002-N includes a user 102 with a television 108/204 and media content player 112, similar to that shown in FIGS. 1-3. Media content players 112 are configured to access aggregate server 1006 as described below. In an embodiment, aggregate server 1006 includes network interface circuit (NIC) 1008, an input/output (I/O) device 1010, a central processing unit (CPU) 1012, a bus 1014, and a memory 1016.

As further described below, users 102 experience media/content using media content players 112. In doing so, users 102 use remotes 106 to change the volume level. In an embodiment, media content players 112 monitor and record volume levels of users 102 and correlate these volume levels with the content being watched. Media content players 112 upload these volume statistics 1018 to aggregate server 1006. Later, when a user 102 wishes to view content, the associated media content player 112 may access volume statistics 1018 of that content from aggregate server 1006. If any volume statistics 1018 exist, media content play 112 may download and apply the volume statistics 1018 while presenting the content to the user 102.

In an embodiment, volume statistics 1018 for a given media/content may vary by time of day. For example, the volume may be lower late at night relative to early evening. Accordingly, aggregate server 1006 may store volume statistics 1018 for a given content based on time of day. Aggregate server 1006 may also select and provide volume statistics 1018 to media content player 112 based on time of day.

Memory 1016 of aggregate server 1006 may include a cluster algorithm 1020, according to an embodiment. The cluster algorithm 1020 causes CPU 1012 to process volume statistics 1018. Such volume statistics 1018 may include N sections of volume statistics 1018 for a particular media for each of environments 1002-N. These volume statistics 1018 may be aggregated to form a crowd sourced repository of volume level changes associated with different points in time in the playback of media.

FIG. 11 is a method 1100 for monitoring, recording, and applying volume statistics for user 102, according to an example embodiment.

In step 1102, media content player 112 may receive media from aggregate server 1006 or some other source, according to an example embodiment.

In step 1104, media content player 112 may check whether the received media includes volume statistics 1018. If yes, then in step 1106 media content player 112 plays the received media on television 108/204 and, while doing so, continually adjusts the volume according to the received volume statistics 1018. If not, then in step 1108 media content player 112 plays the received media using the audio information included therein. Alternatively, media content player 112 may request volume statistics 1018 from aggregate server 1006 and then perform step 1106 upon receipt.

In step 1110, while playing the received media, media content player 112 monitors and records as the user 102 changes the volume level. Media content player 112 correlates any volume changes to the portions of the media being viewed at the time the volume changes were made.

If volume changes were made (as determined in step 1112), then in step 1114 media content player 112 uploads that volume information to aggregate server 1006.

FIG. 12 is a method 1200 for analyzing volume statistics, according to an example embodiment.

In step 1202, aggregate server 1006 receives volume statistics from media content players 112. The volume statistics are mapped to portions of media that were being viewed when volume changes took place.

In step 1204, aggregate server 1006 aggregates and stores the aggregated volume statistics 1018. In an embodiment, aggregate server 1006 aggregates by organizing and averaging volume information by media timeline. For example, assume aggregate server 1006 receives information reflecting multiple volume changes at time t5 of a given content. In an embodiment, aggregate server 1006 averages those volume changes to generate the aggregate volume information 1018 for time t5 of that given content.

In step 1206, media content player 112 requests content.

In step 1208, aggregate server 1006 determines if volume statistics 1018 exist for the requested content. If yes, then in step 1210 aggregate server 1006 provides such volume statistics 1018 to media content player 112. Aggregate server 1006 may also provide the requested content to media content player 112.

Otherwise, in step 1212 aggregate server 1006 may provide only the requested content to the media content player 112.

What is claimed is:
 1. A method for creating a desired audio effect, comprising: causing a plurality of speakers to play test signals, each test signal being specific to one of the speakers; recording frequency responses of the speakers resulting from the playing of the test signals; creating one or more filters to match an audio profile selected by a user; applying the filters to the recorded frequency responses to obtained filtered transformations of the speakers; transmitting the filtered transformations to the speakers; and applying the filtered transformations at the speakers to thereby achieve the user audio profile.
 2. The method of claim 1, wherein the filters are Linear Time Invariant (LTI) filters.
 3. The method of claim 2, wherein the LTI filters comprise at least one of a Finite Impulse Response (FIR) filter and an Infinite Impulse Response (IIR) filter.
 4. The method of claim 2, wherein the filters compensate for delays caused by distances between the speakers and the user.
 5. The method of claim 2, wherein the filters compensate for acoustic anomalies.
 6. The method of claim 1, wherein applying the filters comprises convolving the filters with the recorded frequency responses of the speakers.
 7. A media content device, comprising: a processor operable to: cause a plurality of speakers to play test signals, each test signal being specific to one of the speakers; receive from a remote device recorded frequency responses of the speakers resulting from the playing of the test signals; create one or more filters to match an audio profile selected by a user; apply the filters to the recorded frequency responses to obtained filtered transformations of the speakers; and transmit the filtered transformations to the speakers; wherein the filtered transformations are applied at the speakers to thereby achieve the user audio profile.
 8. The media content device of claim 7, wherein the filters are Linear Time Invariant (LTI) filters.
 9. The media content device of claim 8, wherein the LTI filters comprise at least one of a Finite Impulse Response (FIR) filter and an Infinite Impulse Response (IIR) filter.
 10. The media content device of claim 7, wherein the filters compensate for delays caused by distances between the speakers and the user.
 11. The media content device of claim 7, wherein the filters compensate for acoustic anomalies.
 12. The media content device of claim 7, wherein to apply the filters the processor is operable to convolve the filters with the recorded frequency responses of the speakers.
 13. A tangible computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising: causing a plurality of speakers to play test signals, each test signal being specific to one of the speakers; receiving from a remote device recorded frequency responses of the speakers resulting from the playing of the test signals; creating one or more filters to match an audio profile selected by a user; applying the filters to the recorded frequency responses to obtained filtered transformations of the speakers; and transmitting the filtered transformations to the speakers; wherein the filtered transformations are applied at the speakers to thereby achieve the user audio profile.
 14. A method of using aggregating volume information to enhance audio playback of content, comprising: receiving requested content from a server; determining if the received content includes aggregate volume statistics; playing the received content; continuously adjusting volume of the received content based on the aggregate volume statistics, if it was determined the received content included aggregate volume statistics; monitoring changes in volume made by a user while viewing the received content; and providing information reflecting the monitored volume changes to the server.
